Patent CA-2237776-A1 (CA)
Inventor: DEMPSTER HARRY E
IPC: A63C11/10
Filed: 1996-10-23
Abstract: The device is a portable tractor with attachments for powering skiers, skaters, snowboarders, and the like. It employs a rigid pole to deliver the thrust to a belt which converts the thrust to a pull on the skier's lower back, leaving the skier's arms, hands, legs and feet free to perform their usual skiing functions. The pole also provides leverage to turn the tractor so that it follows the skier's movements. The device provides controls over the tractor's engine to the skier's hands, or to other parts of the skier's body.  The tractor has crawler treads bearing retractable cleats which automatically convert into sled runners so the skier can travel downhill pulling the tractor without dismounting the tractor. The tractor can be folded up and transported by backpack. Various attachments enable use of the tractor to power skates, sleds, snowboards and similar vehicles.

Inventor: PROUST STEPHANE
IPC: G10L19/18
Filed: 1998-04-09
Abstract: The invention concerns a method and a device for coding an audio signal by "forward" and "backward" LPC analysis, the coding being produced by "forward"  LPC filtering for non-stationary zones and on a synthetic signal based on "backward" LPC filtering for stationary zones. For each current LPC block (Bn) (10), the degree of stationarity of the digital audio signal is determined (11), and a "forward" or "backward" LPC analysis selection value is established (12) based on a decision function, according to the stationarity parameter. A "forward" or "backward" LPC analysis criterion is applied (13) to the analysis selection value to produce the audio signal coding before proceeding to the next LPC block. The invention is applicable to mobile radiotelephony, to the production, memorisation of audio recordings, to the transmission by satellite and wideband telephony.

Abstract: In multistage refrigeration compression (10), where liquid refrigerant withdraw from a core-in-shell type heat exchanger (40) connected to a high compression stage (16) is passed to a similar exchanger (70) connected to a lower compression stage (14), liquid level stability in the higher compression stage exchanger (40) is improved by providing an enlarged surge volume. A baffle plate (50) transversing a lower portion of the shell divides the shell into a cooling zone that contains the cores, and a discharge zone that is part of the surge volume. The height of the baffle is selected to facilitate maintenance of at least a minimum functional liquid level in the shell. Liquid refrigerant withdrawn from the discharge zone of the high-stage shell is supplied to the cooling zone of a shell connected to a lower compression stage. The liquid level in the shell is maintained by manipulating flow to liquid refrigerant that is flashed into the cooling zone of the higher compression stage shell.

Abstract: Gas generant compositions are disclosed that generally include a fuel source including a compound having a fuel portion and a fuel oxidizing portion, a fuel oxidizer, and a borohydride catalyst of the oxidation of said fuel portion by said fuel oxidizing portion and said fuel oxidizer to produce gaseous reaction products. In preferred compositions the fuel source is comprised of the elements nitrogen, carbon, hydrogen and water and combusted to produce N2, CO2 and H2O as the primary reaction products. Preferably, the fuel oxidizer is a metal nitrate, and particularly potassium nitrate, because the potassium will generally be included in solid products and not in the form of a potentially harmful gas. It is also preferred that the combustion reaction be catalyzed using borohydrides. Potassium borohydrides, such as K2B12H12 and K2B10H10, are particularly preferred. In addition, binding materials, and dry lubricants or processing aids are included, when compositions are used in pellet or tablet form. The compositions detailed in this invention react at relatively high rates and they produce large quantities of gas within fractions of seconds. In addition, these compositions produce only small amounts of slag which are readily filterable. The gases produced are then available to perform a work function in automotive safety restraint systems such as seat belt pretensioners and automobile air bag inflators, as well as in other inflatable device applications, such as lifesaving buoying devices, life rafts and aircraft slides.
